12V / 24V / 230V protection relay for PTC probes, 1 or 2 outputs, type 17,5mm

Description

A maximum of 6 thermistors can be connected to sensor terminals P1 and P2. The relay power supply (12V AC / DC, 24V AC / DC, 230V AC) is connected to terminals A1 and A2. The green LED indicates that the relay is energized.

Function

The ZTH uses a closed circuit principle, the relay output switches immediately to its working position as soon as the resistance of the sensor is less than 1,5KOhms. After the thermistor has reached its nominal temperature (resistance> 3,2KOhms), the relay switches to its rest position. This status is indicated by the red LED.

The measuring circuit is electrically isolated from the power supply.
